Just a wee heads up folks spent a while messing around trying to get into the service menu to reset the RGB balance ( press menu on remote nad set and hold until service menu pin number request appears 0000 or 1234 is the default if it's been changed your in bother ) anyway the pin had been changed on this one so couldn't get into menu. Shorted the data and clock pins on the eprom ( pins 5&6) powered up board, removed short and rebooted and hey presto pictures perfect saved a lota hassel !
